Here's a quick rundown of what we think we know about the AL's closer situations.

Orioles: Tommy Hunter. This is just an educated guess, as Hunter, Darren O'Day, Ryan Webb and even Brian Matusz could all be in competition this spring.

Red Sox: Koji Uehara. Last year's record-setting season hopefully erased concerns about his ability to close and his durability.

Indians: John Axford. Axford is a "proven closer," which should give him first crack at this job, but Cody Allen, Bryan Shaw and Vinnie Pestano have "closer stuff," too.

White Sox: Nate Jones. Jones has been solid in middle relief the past two years, and with little competition outside of Matt Lindstrom, it will be his job to lose.

Tigers: Joe Nathan. Even at 39, Nathan is one of the best.

Astros: Josh Fields: Your guess is as good as ours here. Fields closed for a while last year and has a high K-rate, but it's tough to tab a frontrunner between him, Chia-Jen Lo and newcomer Jesse Crain.

Royals: Greg Holland: As good as it gets in the AL.

Angels: Ernesto Frieri: Angels' manager Mike Scioscia will almost certainly pull Frieri from the closer's role at some point — regardless of whether he deserves it — but Frieri should start the season with ninth-inning gig.

Twins: Glen Perkins: Proved to be a fantastic closer last year, but his ability and lefthanded-ness makes him a potential trade chip.

Yankees: David Robertson: With no competition for the job, Robertson should start the season as New York's closer, making him a major sleeper.

A's: Jim Johnson: Led the league in saves the past two years, but Oakland has no shortage of replacement options (Luke Gregerson, Ryan Cook, Sean Doolittle) if Johnson struggles like late last season.

Mariners: Fernando Rodney: Well, we thought sleeper Danny Farquhar was going to get a shot at closing until this happened. Given Rodney's age and control issues, Farquhar still might get his chance.

Rangers: Neftali Feliz: Feliz is currently listed as the "closer" on the Rangers' website, but Joakim Soria will challenge him.

Blue Jays: Casey Janssen: Pitched well and stayed healthy last year, distancing himself from Sergio Santos.
